The $20 ticket package covers all four games. I bought 2 tickets and it came to $70 ($40 for the tickets plus $30 of useless fees from Ticketmaster).
Agreed about it not being very crowded, it seemed all sections had openings when I was looking about a month ago.
I'm in section C102, Row 2. Feel free to swing on by, it'd be nice to meet another ss.com poster!
It sounds like the area around the arena is pretty empty...is that about right? Our hotel is about 20 minutes away as well according to Google maps. I'll be there with the wife and daughter.
